Made in 1807 by Hosiah Amsbary, these bizarre magical spectacles were used by generations of the Amsbary family to see into other dimensions. There were various sets of lenses which could be fit into the frames, each of which afforded a different kind of view.
The prop is a modified antique blindfold, which was allegedly used in secret rituals of the Oddfellows Lodge, acquired from a Colorado antique dealer years before the game was played.
Two pairs of custom lenses were constructed for the game. One pair acted simply as red filters to allow the players to see hidden text in a book. The other pair used fragments of mirror to enable players to see in front of them with one eye, and to see things off to the side with the other eye, simultaneously. Sadly, both pairs of lenses have since been lost.
